Hi Katalon Team,
I am trying to run an .ipa App on my iOS simulator using Katalon studio. But every time I try running it, it gives me the following error :
Unable to start application on this device. Xcode version 0.0 : Support for Xcode 0.0 is not supported. Please upgrade to version 7.3 or higher.

The details are as under :
Appium version : 1.8.1
Katalon studio version : 5.7.1
Xcode version : Version 10.0 (10A255)

Hey Chris,
Thanks again man. You are a savior. I am able to launch the iOS App from Katalon Studio now on iPhone simulator. But I think I am facing chain of issues at each progressive step, especially for iOS.

The other problem I am facing is :
The App terminates as soon as it launches. There are the following error messages that gets displayed :

[XCUITest] Simulator architecture appears to be unsupported by the ‘{App Path}’ application. Make sure the correct deployment target has been selected for its compilation in Xcode.

Next, I would check how the app you’re testing is built and signed. Unfortunately, you probably won’t be able to test a .ipa file because those are not created to be run on simulator architectures. Instead, you should try to test the .app file, which will be unsigned (you may need to get this directly from a developer).

I think the issue you’re seeing now is that an .app file can be built for a real device or a simulator (these have different architectures - arm vs. x86, respectively). In order to run the test on your simulator, your dev will need to build the .app file while selecting a simulator instead of a real device.

Alternatively, your developer may be able to build the app by setting “Build Active Architecture Only” to “No”.

I followed your suggestion of having two versions of XCode. But iOS devices which are running on 12 are not supported with XCode 9.4.1. In this case what needs to be done .

i get this error everytime i try to run the build from command line.
NSLocalizedRecoverySuggestion = “This iPhone 6s Plus is running iOS 12.1 (16B92), which may not be supported by this version of Xcode.”;

Unfortunately, you’re correct that you can’t run the tests on an iOS 12 device because those simulators require Xcode 10 to be the active version. If you want to run the tests, you’ll only be able to run them on iOS 11 and lower devices until Katalon Studio supports Xcode 10.
